Pin sessions / custom sort order in session history sidebar

Problem Statement

Feature request: Pin sessions and/or custom sort order in the session history sidebar (VS Code extension).

Problem: The session list is always sorted by last-activity/recency. Opening or continuing any session bumps it to the top, so sessions constantly reorder and I lose track of where they are. Renaming with number prefixes ("1.", "2.", "3.") does NOT help because the list sorts by time, not by name.

Request:
1) Ability to PIN specific sessions so they stay at the top in a fixed position.
2) An option to sort the list alphabetically by name (and/or manual drag-to-reorder), so numbered/named sessions keep a stable, predictable order.

Use case: I run many parallel sessions per project (config, UI/giao diện, QA, server, etc.) and need them in a consistent order to navigate quickly, instead of them jumping around every time I reopen one.
